The number of Muslims in the world has been increasing steadily over the years, and they are now the second-largest religious group, after Christians. Religious dynamics are rapidly changing around us due to fertility rates, youth population among varying religious communities, and conversions. Islam is the fastest growing religion in the world. The share of the Muslim world’s contribution to the global economy is disproportionate to the size of their population, but the Islamic world offers immense potential with a wealth of natural resources.
